7 Claims. (01. 2863) The invention relates to a; singeing machine and more especially to an automatic singeing ma% chine for yarn, thread, cloth or other material.

The primary object of the invention is the provision of a machine of this character wherein two sets of burners are employed, one of which burns from the time the machine is started untilit is stopped, the other burns until the unsinged portion. has passed over the first burner m, and has been singed, whereupon the [second burner is automatically turned down to non-singeing position and upon the stopping of the machine the fuel is partially cut off and the yarn or thread or other material operated upon is raisedfrom the burners and protected therefrom automatically by the use of shields. i

Another object of the invention is the provision of a machine of this character wherein material to be singed ismoved over burners, these being automaticallycontrolled so as to efliciently remove the lint and trim the loose projecting fibers from the surface of the threads'or other.

material, the machine in its entirety being of novel construction and automatically operated,

,25 thereby eliminating any manual control of such machine; g v v r 1 A further object of the invention isthe provision of a machine of this character, wherein the same is operated either directly by a warp machine or may be driven independently thereof and will singe threads, yarns, cloth or the like so as to remove therefrom lint, fluff or loose particles, the'thread or other material operated upon being protected so as to avoid burning or scorch- 35. ing thereof should the feed of the material be stopped during the si-ngeing operation of the machine. r 1 i A still further object of the invention is the provision of amachine of this character wherein .40. the feed to the burners and also the burners are automatically controlled in a novel manner and during the singeing operation the burners are automatically moved to the work and the fuel thereto regulated and upon the stopping of the machine .the work is automatically lifted while gas through. saidbranches 15 fora purpose prescombination and arrangement of parts as will be hereinafter more fully described in detail, 11- lustratedin the accompanying drawings, which disclosethe preferred embodiment of the inven: tion, and pointed out in the claims hereunto appended.

V V r Figure 9 is a perspective. view of the clutch lever. 1 t Figure 10 is a perspective view of the releasing member for the clutch lever. I

Similar reference characters indicate corresponding parts throughout the several views in the drawings. Referring to the drawings in detail, the ma-. chine comprises a stand A in the form of aframe 10 havingv the upper and lower longitudinal side bars or rails 11 and 12 respectively and the vet-r tical supporting legs 13, Within thisframe ;l() is mounted a gas supply pipe 14 leading from any 1 suitable source of supply and is provided with the branches 15, the vertical stretches 16 of which have fitted therein turn valves l7, these being automatically operated to vary the flow of ently described. a

Journaled in the upper side rails 11 of the frame 10 near opposite endsof the latter are the hollow axles 18-for swinging gas burners 1 9 and 20 respectively and communicating with these axles 18 are the vertical stretches 16 of the Il branches 15 from the supply pipe 14 so that fuel ean be fed to the burners. The burners 19 and 20 each have short pipe connections 21 with its hollow axle 18. The hollow axles 18 each is fitted with weighted balancing arms 22:

Arranged at the right hand end of the frame 10 is a work guide 23 and in this instance there is trained therethrough Warp threads 24, these being fed into a warp machine (not shown) with which the singeing machine is to be associated. The feed of the threads 24 is in the direction from the right hand end to the left hand end of the frame -10 above the top thereof, while the burners 19 and 20 are disposed transverselyoi this frame and are adapted to be swung into operative position with respect to the threads 24 when being fed to the warp machine in a manner presently described.

.Journaled in the lower side bars 12 next to the spring'31, the. same being disposed betweenthe' Windlass 29 and'the slide ,ring32 loose on said shaftiand connectedwitha' clutch throw lever 33'pivoted' at 34 to abracket 35' stationarily arranged in the frame 10.

when: shifted in one direction tensions the spring 31 so as to move 'the member 27 into engagement with the member 26 ofthe'clutch so that power from the belt wheel 30 will be transmitted through said shaft 25, members 26'and'27 of the clutch to the disk'28 and'the'windlass 29 for a shown) so that upon the, starting of said wa rp I moved to singeing position with respect to the threads 24' constituting the work'to'be singed.

purpose presently described. s w Suitably journaled in the side rails or bars 12 of the frame 10 are the rocking shafts 36 and 37 respectively and this shaft 36 has fixed thereto the crank arms 38 and 39, the'latterhaving pivoted-at 40* thereto a link 41 which is also pivoted at 42m the crank arm 43 on the hollow axle 18 of the burner'1-9. 4 The arm 38 has pivoted thereto the connecting rod 44 pivoted also atj45 withthe'crank arm'46 on the shaft 37. r This shaft, through the'crank arm 48 and link 49, has connection with a bell crank '50 which is operated by 5 connection 51 from the warp machine (notmachine theburner 19' will be automatically The valve 17, through the lever 52, has connection with the 111116 41 so that upon moving the.

burner 1 9 to the work the said valve 1'7 will be automatically opened through arm'52 for increas- -ingthe gas supply to said burner for the singeing operatiom H 1 I fixed to thehollow axle'18 of the burner: 20

is a disk 53. having the peripheral detent notch 54 therein and eccentrically pivoted at-55 there-f to a throw' rod 56;the latter slidably fitted in a guide 57 carried by the frame 10; The rod 56 is formed with a ratchet notch 58 for a feed dog 59swingingIy mounted at 60'and movable by a: link fil pivoted thereto. This'link-Gl is pivoted to a crank :arm' 62 on the axle 18 of the burner 19 Thus it will be seen thatwhnfthe burner. 19 1S,

' in Figure 2 This clutch lever 38 swung to working position the link 61 will move the dog 59 which is engaged in the notch 58 of the rod 56 to turn the disk 53, whereby the burner 20 will be raised to working or singeing position. This disk 53 also has pivoted thereto a link 63 which is pivoted to the arm 64 for operating the valve 17 in the vertical stretch 16 of the branch 15 of the supply pipe 14 leading to the burner 20 so that the flow of gas'to the latter will be automatically controlled under the movement of said disk 53 and when the burner 20 swings to working position the valve will be opened to increase the supply to said burner.

The shaft 37 has fixed thereto the crank arm 65 to which is pivoted a trip rod 66, the latter slidably through a guide 67 at the top of the frame 10; The frame at its top has pivoted at 66 thereto the detent 69 which is engageable by gravity in the notch 54 injthe disk 53 when the latter is turned to bring the burner 20 in working position so that the detent 69 when engaged in the notch 54 will hold said burner 20 in its raised working position until the rod 66 which is in the path of said detent 69 releases the same from the notch 54, whereuponthe burner 20 will recede to non-working or nonsihgeing position as is shown of the drawings.

-'On the frame 10 and suitably projected there from is a stop 70 with which engages an abutmerit pin 71 on the disk 28 and connected with the hub 29'constitutin g" the Windlass is one end of a winding and unwinding strap '72 having a weight 73 at its free end, thestrap '72 being automatically wound upon said Windlass 29 and by the weight 'l thereon the pin '71 will be brought into abutting position with the stop 70 forthe resetting of said disk 28 when the members 26 and 27 of the clutch are disengaged from each other for a purpose presentlydescribed. a

The pin' 71 when moved clockwise is adapted to engage with a projection 74' of a trip rod 75 slidable in a guide '76 and also the guide 67, the trip rod '75 being adapted to trip the detent 69 from engagement in the notch 54 in the disk 53 so as-to permit the burner 20 to move to nonsingeing position whenthe same has been shifted to singeing position. V

Formed in the hub 29 is a cam 77 which operates upon: a clutch release member '78 swingingly supported upon the shaft 37. The release memb'er'78' is "arranged in the path of a tripping wing 79 hinged upon a throwrod 80 pivoted to a crank arm 81'on the shaft 36 'andslidable through a guidebracket 82 on the frame 10 of themachinej This wing '79 when not'acted upon by'the member '78 and moved bythe arm 81 on the shaft 36 will operate upon the throw lever 33 to move the same for the bringing of the members 26 and 27 of the clutch into engagement with each other and when the member 78 operates'upon the wing '79 the latter is swung out of engagement with the clutch lever; 33 so that the members 26 and 27.

of the clutch will be released from each other and said clutch opened.

In the operation of the machine, assuming that the warp machine'is started and the parts of the singeing machine are in the position as shown in Figure 2 of the drawings which is neutral position thereof, the instant the'warp machine is started the bell crank 50 is shifted by the right hand end of the-frame 10 to the left hand end thereof into the warp machine, it beingum derstood of course-that a'suflicient amount of fuel is delivered to the burners 19 and 20 so that the same will be flamed and when the burner 19 is raised to working position the valve 52 is fully open so as toincreasethe flame of the burner 19 for the action thereof in singeing the thread 24. Simultaneously with theshifting of the burner 19 the feed dog 59 will be operated by the rod61 to throw the feed arm 56 in a direction to turn the disk 53 and byso doing the burner 29 will be lifted from its lowered position in Figure 20f the drawings to singeing position and likewise the gas flowing to said burner 20will-be increased for the full flaming thereof. In this working position of the burner 20 thedetent 69 will engage the notch 54 in the disk53, thereby holding said burner 20 in its working position. This burner 20 singes the threads 24 on the advance portion thereof between the warp machine and the burner 19, that is, for the length of the threads overlying the frame 10 of the machine between the locations of the burners 19 and 20 and immediately upon the singeing of this determined stretch of such threads 24 the burner '20 is automatically lowered to non-singeing or nonworking position. This lowering of the burner 20 under the automatic action of the machine is controlled by the trip rod 75 operated upon by the pin 71 which under its clockwise travel engages with the projection 74 on the rod 75. Timed with the pin '71 is the cam I'Zwhich controls the release member 78' for actuating the wing 79 to move the same out of engagement with the clutch throw lever 33 whereby the clutch will be opened by the disengagement of the members 26 and 2'7 thereoffand thusthe disk 28 will be freed'while under the action of the strap '72 and weight 73 the said disk will be turned counterclockwise, bringing the pin 71 thereon into engagement with the stop and thus the trip rod Wi11 be lowered to neutral position.

The dog 59 has formed therein a kicking tine non-singeing position as shown in Figure 2 of the drawings the shields ,84 will overhang the same and eliminate the heat or flames of such burners reaching the threads 24 or the work. The axle 18 for the burner 19 operates lifters 35 and 86 respectively for the threads 24 to elevate the same when the burners 19 and 20 are in lowered non-singeing position, thereby holding such threads considerably away from such burners so as not to be affected by the flames issuing therefrom, it being understood of course that when these burners are in their lowered position the valves 17 'will have been automatlcally partially closedso as to reduce the flames of such burners.

Should the warp machine become stalled for any reason and the burner 19 and also the burner 20 being in singeing position, the same will be automatically lowered under the action of the connection 51, bell crank 50, the rods 41 and 66 respectively so that the threads 24 will not become burned or scorchedas the burners l9 and 20 will become lowered tion.

It will be understood of course that in the working of the singeing machine the burner 19 is pre-- sented to the work, that is, the threads 24, and simultaneously therewith the burner 20 is presented to the work and this burner 20 is timed to recede from the work automatically after the.

stretch of the work lying between the warp machine and the burner 19 has become singed because the remainder of the work at the right hand side of the burner 19 will be singed thereby as the work is moved into the warp machine.

As has been previously indicated, should a thread 24in the work fed over the singeing machine break during the singeing operation the burner'19 will be automatically lowered to nonsingeing position andthe' shield 84 will lie directly between the lowered-burner 19 and such threads while the latter will be elevated a determined height by the members 85jand 86- as hereinbefore described. v
